Fuel Gauge

my guage does the same thing, using 02 cluster, but 83 sending unit, it is because the newer tanks use a 33 -240 ohm sending unit, older one uses a 0-90 ohms, your sending unit is prob. a 0-90 ohms

Is there anywhere I can run the fuel gauge wire to so it can pickup the signal for fuel level?
